The downside: due to a combination of the ebook formatting and my old Kobo, the chapter breaks weren't clearly indicated; there were a couple of times where I missed the scene change and had to skip back a paragraph to pinpoint where it had happened.

Besides that: it was a sweet, interesting story that wasn't too heavy on the grue and body horror (I mean, it had some, as one does when writing a story about monsters that jigsaw people to pieces and extract their bones). Premise is interesting, characters are sympathetic and plausible, research and unfolding of the mystery makes sense. I'd look up further works by the author.
